Dishwashers

Modern dishwashers clean dishes thoroughly and use less power and water than washing up by hand if you apply the following tips:

The right size: When buying a new dishwasher, make sure it is the right size for you. However, it is worth noting that a standard appliance with capacity for 12 to 15 place settings uses proportionately less water than a smaller appliance for up to nine place settings. It is therefore more economical to use a large appliance less frequently.

Full loads: Only wash the dishes once the machine is full. A half-empty appliance uses just as much power and water as a full one. Put used dishes in the machine and always keep the door closed to prevent leftovers from drying onto plates.

Avoid prewashing: You can usually do without prewashing under running water. Removing large leftovers from the dishes is sufficient. Only select the pre-wash program if the dishes are extremely dirty.

Select the right program: Select the right program for the type of dishes and level of dirt. The intensive program is only required for very dirty dishes. Select the energy-saving program for normal levels of dirtiness.

Take account of water hardness: Measure out your dishwasher’s rinse aid solution based on the water hardness. Chalky water leaves a film which increases power consumption. You should therefore de-scale your dishwasher regularly.

Avoid stand-by mode: Only use the timer if absolutely necessary as it includes a stand-by phase when electricity is consumed. Equally important, switch the appliance off as soon as the wash program has finished.

Hot water supply: You can save electricity by connecting the dishwasher directly to the hot water supply. The use of a heat pump, solar system or district heating is also extremely efficient.
